La Golondrina & La Costa Meadows Sewer Extensions Project Title 2009021109 City of Carlsbad, Pam Drew (760) 602- 4644 State Clearinghouse No. Lead Agency, Contact Person Telephone Number Project Locations (include County) The La Golondrina sewer extension project is located between La Golondrina Street and Vermarine Court. A portion of the pipeline extension will be within the street right-of-way on La Golondrina Street and the other portion will be constructed by Horizontal Directional Drilling (HDD) under an open space preserve to connect to an existing pipeline on Vermarine Court. The La Costa Meadows sewer extension project is located between Chorlito Street and El Fuerte Street. A portion of the pipeline extension will be within the street right-of-way on El Fuerte Street and the other portion will be constructed by HDD under an open space preserve. The two existing sewer lift stations are located on residential lots (APN: 215-561-20 and 215-380-14). A sewer service area boundary adjustment between the Leucadia Wastewater District and the City of Carlsbad will encompass 70 additional lots, which are currently serviced by the Leucadia Wastewater District. The 70 lots are located north and east of the La Costa Meadows sewer extension project (Figure 5). The properties are located in Township 12 South, Range 4 West, and Section 24 of the Encinitas U.S. Geological Survey (USGS) topographic quandrange map. Specifically, east of Interstate 5 (1-5), south of Palomar Airport Road, north of La Costa Drive, and west of Melrose Drive within the City of Carlsbad, County of San Diego. Name of Applicant: City of Carlsbad Applicant's Address: 1635 Faraday Avenue, Carlsbad, CA 92008 Applicant's Telephone Number: (760) 602-4644 Project Description: The project includes the construction of two gravity flow sewer pipeline segments, which will allow for the abandonment of two temporary sewer lift stations. The pipeline segments are referred to as the La Golondrina and La Costa Meadows Sewer Pipeline Extensions. The La Golondrina sewer extension includes the construction of approximately 1,000 lineal feet of 8- and 10-inch diameter pipeline, of which approximately 800 lineal feet of 10-inch diameter pipeline will be constructed by Horizontal Directional Drilling (HDD) method. Two new manholes will also be installed. Both manholes will be located within La Golondrina Street. Approximately 300 lineal feet of existing 8-inch diameter sewer pipeline will be abandoned in place. The pipe will be cut, filled with sand, and capped with a concrete plug. The contractor will remove and salvage existing above ground and underground pumps, valves, piping and other appurtenances to the existing sewer lift station. The remaining underground structures will be backfilled with sand or soil. Revised December 2004 The La Costa Meadows Sewer Extension includes construction of approximately 500 lineal feet of 10-inch diameter pipeline by HDD method and 1,300 lineal feet of 8-inch diameter pipeline by traditional open trench methods within the street right-of-way. Eight new manholes will also be installed. No manholes will be installed within the open space preserve. Approximately 1,000 lineal feet of existing 6-inch diameter sewer force main pipeline will be abandoned in place. The pipe will be cut, filled with sand, and capped with a concrete plug. The contractor will remove and salvage existing above ground and underground pumps, valves, piping and other appurtenances to the existing sewer lift station. The remaining underground structures will be backfilled with sand or soil. The HDD method will be used to avoid impacts to environmentally sensitive habitat on both alignments. Both sewer pipeline extensions are part of the City's Capital Improvement Program, hi addition, a pending agreement between the City of Carlsbad and the Leucadia Wastewater District will allow the District to detach the specified properties now in the District service area from the District through a formal Local Agency Formation Commission (LAFCO) Detachment proceeding (wastewater service area boundary adjustment). This is to advise that the City of Carlsbad has approved the above described project on April 10, 2009, and has made the following determination regarding the above described project. 1.

PROPOSED DETERMINATION: The City of Carlsbad has conducted an environmental review of the above described project pursuant to the Guidelines for Implementation of the California Environmental Quality Act (CEQA) and the Environmental Protection Ordinance of the City of Carlsbad. As a result of said review, the initial study (EIA Part 2) identified potentially significant effects on the environment, but (1) revisions in the project plans or proposals made by, or agreed to by, the applicant before the proposed negative declaration and initial study are released for public review would avoid the effects or mitigate the effects to a point where clearly no significant effect on the environment would occur, and (2) there is no substantial evidence in light of the whole record before the City that the project "as revised" may have a significant effect on the environment. Therefore, a Mitigated Negative Declaration will be recommended for adoption by the City of Carlsbad Planning Director. 1635 Faraday Avenue * Carlsbad, CA 92008-7314 <• (760) 602-4600 <> FAX (760) 602-8559 « www.ci.carlsbad.ca.us A copy of the initial study (EIA Part 2) documenting reasons to support the proposed Mitigated Negative Declaration is on file in the Planning Department, 1635 Faraday Avenue, Carlsbad, California 92008. Comments from the public are invited. Pursuant to Section 15204 of the CEQA Guidelines, in reviewing Mitigated Negative Declarations, persons and public agencies should focus on the proposed finding that the project will not have a significant effect on the environment.

PROJECT DESCRIPTION: The project includes the construction of two gravity flow sewer pipeline segments which will allow for the removal of two temporary sewer lift stations, which are currently on two separate residential properties. The pipeline segments are referred to as the La Golondrina and La Costa Meadows Sewer Pipeline Extensions. The La Golondrina sewer extension includes the construction of approximately 1,000 lineal feet of 8- and 10-inch diameter EIA 08-01 LA GOLONDRINA & LA COSTA MEADOWS SEWER EXTENSIONS pipeline of which approximately 800 lineal feet will be constructed by Horizontal Directional Drilling (HDD) method, which is a trenchless method (Figure 3). The La Costa Meadows Sewer Extension includes construction of approximately 500 lineal feet of 8- and 10-inch diameter pipeline by HDD method and 1,300 lineal feet by traditional open trench methods within the street right-of-way (Figure 4). The HDD method will be used to avoid impacts to environmentally sensitive habitat on both alignments. Both sewer pipeline extensions are part of the City's Capital Improvement Program. CONSTRUCTION DESCRIPTION: Both sewer extension projects will use both open trench and HDD methods to install the gravity sewer pipelines. The HDD method will occur within the City's Habitat Management Plan Hardline Preserve Areas (HPA) so as not to disturb any sensitive habitat, and the conventional trenching method will occur within the street right-of-way. The HDD requires an approximate 10-foot by 30-foot pit at each end of the tunneling to allow the drill rig to start the reaming process, and at the other end for pipe pull-back operations. According to the La Golondrina and El Fuerte Street HDD Sewer Extension Preliminary Design Report, prepared by Dudek, and dated March 2008, a small diameter drill head is extended along a pilot bore path with hollow drill string pipe pushing it forward. Bentonite slurry will be used as a drilling lubricant. Bentonite is an absorbent aluminum phyllosilicate, generally impure clay consisting mostly of montmorillonite. Bentonite usually forms from weathering of volcanic ash, most often in the presence of water and is non-toxic. The bentonite slurjy is lifted to the drill head under pressure and exits through the cutting nozzle on the drill head arid carries spoils back to the drill rig through the drilled hole. The spoils will not be deposited into any habitat areas. The pilot bore is extended to the "exit side" or "pipe side" of the HDD installation. Once the pilot bore exits the ground at the intended location, and the bentonite slurry is recovered, a back reamer is attached to the drill string and pulled back to the drill rig. The pipe is attached to the string and pulled through the tunnel. The bentonite slurry will be collected in the exit pit and pumped into a holding tank and removed from the site. The slurry will be reused by removing the sand that will get mixed in with the slurry during the drilling process. One of the risks associated with HPDD is the escape of drilling mud into the environment as a result of a spill, tunnel collapse or the rupture of mud to the surface, commonly known as "frac-out." A frac-out is caused when excessive drilling pressure results in drilling mud propagating toward the surface. The risk of a frac-out can be reduced through proper geotechnical assessment practices and drill planning and execution. The extent of a frac-out can be limited by careful monitoring and having appropriate equipment and response plans ready in the event that one occurs. A mitigation measure has been included to require the contractor to prepare an Emergency Frac-Out Containment Plan and submit it to the Engineering Department for review. The pipeline extension for La Golondrina will be installed to a depth between 8-feet and 52-feet (the dept varies depending on the topography). The depth for the La Costa Meadows pipeline will vary between 4-feet and 22-feet deep. Both ends of the new sewer pipeline will be attached, via open trench, to new or existing sewer lines. The open trench method will be constructed within the street right-of-way at a minimum depth of 5-feet. During trenching, the spoils will be placed in an approved area by the City's inspector either within the public right-of-way or within disturbed areas. No spoils will be stored within the habitat preserve. The spoils will be protected from erosion in compliance with the City's National Pollutant Discharge Elimination System Permit (NPDES) and approved Best Management Practices (BMPs). The staging areas for both pipeline extensions will be within disturbed areas of ornamental vegetation and within the street right-of-way. Rev. 11/17/08 EIA 08-01 LA GOLONDRINA & LA COSTA MEADOWS SEWER EXTENSIONS BACKGROUND: The construction of both sewer pipelines is required by two separate agreements between the City of Carlsbad and Leucadia Wastewater District. Both agreements provided for the City of Carlsbad (City) to temporarily direct wastewater flow into the Leucadia Wastewater District's (District) collection system until development in the adjacent area would allow for the extension of Carlsbad's sewer system. Recent development in the area now allows for the gravity sewer pipeline connections, which will convey wastewater into City's sewer system instead of the District's sewer system. The construction of the La Golondrina Sewer Extension will allow for the removal of the City- owned La Golondrina Lift Station. The La Costa Meadows Sewer Pipeline Extension will allow for the removal of the La Costa Meadows 3 Lift Station (LCM 3), which is owned and operated by the District. LCM 3 now provides wastewater service for properties in both the District and the City service areas. All of the properties are within the City's boundary. With the removal of LCM 3, the wastewater will flow by gravity into the City's service area. The City and District have agreed that the proposed gravity flow system replacing LCM 3 along with a boundary adjustment between the two service areas will benefit the region with a more efficient collection system reducing operational and maintenance costs. A pending agreement between the City and the District will allow the District to detach the specified properties (see Attachment 5 for properties) now in the District service area from the District through a formal Local Agency Formation Commission (LAFCO) Detachment proceeding (wastewater service area boundary adjustment). ENVIRONMENTAL SETTING: Both sewer extension pipelines will be constructed partially through the City's Habitat Management Plan Hardline Preserve Areas (HPA) and within the public right-of-way. However, the areas through the HPA will be constructed using the HDD method, which is a trenchless method and avoids direct removal of sensitive vegetation. The HPA's are owned and maintained by the Rancho Carrillo Master Association (APN 222-662-26), Ponderosa Country Homeowners Association (215-561-46), and La Costa Greens Community Association (213-231-25). The existing sewer lift stations are located on residential properties surrounded by ornamental vegetation. The lift stations are on concrete pads. The concrete pads will be removed. SURROUNDING LAND USES: The surrounding land uses are Open Space (OS), Residential Low-Medium (RLM) density housing, Secondary Arterial Streets, and Undesignated Streets. In addition, a RV storage lot is located off of El Fuerte Street, just south of Rancho Pancho. Rev. 11/17/08 EIA 08-01 LA GOLONDRINA & LA COSTA MEADOWS SEWER EXTENSIONS ENVIRONMENTAL FACTORS POTENTIALLY AFFECTED: The summary of environmental factors checked below would be potentially affected by this project, involving at least one impact that is a "Potentially Significant Impact," or "Potentially Significant Impact Unless Mitigation Incorporated" as indicated by the checklist on the following pages.

(To be completed by the Lead Agency) I find that the proposed project COULD NOT have a significant effect on the environment, and a NEGATIVE DECLARATION will be prepared. Kt I find that although the proposed project could have a significant effect on the environment; there will not be a significant effect in this case because the mitigation measures described on an attached sheet have been added to the project. A MITIGATED NEGATIVE DECLARATION will be prepared. I find that the proposed project MAY have a significant effect on the environment, and an ENVIRONMENTAL IMPACT REPORT is required. I find that the proposed project MAY have "potentially significant impact(s)" on the environment, but at least one potentially significant impact 1) has been adequately analyzed in an earlier document pursuant to applicable legal standards, and 2) has been addressed by mitigation measures based on the earlier analysis as described on attached sheets. A Negative Declaration is required, but it must analyze only the effects that remain to be addressed. I find that although the proposed project could have a significant effect on the environment, there WILL NOT be a significant effect in this case because all potentially significant effects (a) have been analyzed adequately in an .earlier ENVIRONMENTAL IMPACT REPORT or NEGATIVE DECLARATION pursuant to applicable standards and (b) have been avoided or mitigated pursuant to that earlier ENVIRONMENTAL IMPACT REPORT or NEGATIVE DECLARATION, including revisions or mitigation measures that are imposed upon the proposed project. Therefore, nothing further is required. Planner Signature Date Planning Director's Signature Date Rev. 11/17/08 EIA 08-01 LA GOLONDRINA & LA COSTA MEADOWS SEWER EXTENSIONS ENVIRONMENTAL IMPACTS STATE CEQA GUIDELINES, Chapter 3, Article 5, Section 15063 requires that the City conduct an Environmental Impact Assessment (EIA) to determine if a project may have a significant effect on the environment. The Environmental Impact Assessment appears in the following pages in the form of a checklist. This checklist identifies any physical, biological and human factors that might be impacted by the proposed project and provides the City with information to use as the basis for deciding whether to prepare an Environmental Impact Report (EIR), Negative Declaration, or to rely on a previously approved EIR or Negative Declaration. • A brief explanation is required for all answers except "No Impact" answers that are adequately supported by an information source cited in the parentheses following each question. A "No Impact" answer is adequately supported if the referenced information sources show that the impact simply does not apply to projects like the one involved. A "No Impact" answer should be explained when there is no source document to refer to, or it is based on project-specific factors as well as general standards. • "Less Than Significant Impact" applies where there is supporting evidence that the potential impact is not significantly adverse, and the impact does not exceed adopted general standards and policies. • "Potentially Significant Unless Mitigation Incorporated" applies where the incorporation of mitigation measures has reduced an effect from "Potentially Significant Impact" to a "Less Than Significant Impact." The developer must agree to the mitigation, and the City must describe the mitigation measures, and briefly explain how they reduce the effect to a less than significant level. • "Potentially Significant Impact" is appropriate if there is substantial evidence that an effect is significantly adverse. • Based on an "EIA-Initial Study", if a proposed project could have a potentially significant adverse effect on the environment, but all potentially significant adverse effects (a) have been analyzed adequately in an earlier EIR or Mitigated Negative Declaration pursuant to applicable standards and (b) have been avoided or mitigated pursuant to that earlier EIR or Mitigated Negative Declaration, including revisions or mitigation measures that are imposed upon the proposed project, and none of the circumstances requiring a supplement to or supplemental EIR are present and all the mitigation measures required by the prior environmental document have been incorporated into this project, then no additional environmental document is required. • When "Potentially Significant Impact" is checked the project is not necessarily required to prepare an EIR if the significant adverse effect has been analyzed adequately in an earlier EIR pursuant to applicable standards and the effect will be mitigated, or a "Statement of Overriding Considerations" has been made pursuant to that earlier EIR. • A Negative Declaration may be prepared if the City perceives no substantial evidence that the project or any of its aspects may cause a significant adverse effect on the environment. • If there are one or more potentially significant adverse effects, the City may avoid preparing an EIR if there are mitigation measures to clearly reduce adverse impacts to less than significant, and those mitigation measures are agreed to by the developer prior to public review. In this case, the appropriate "Potentially Significant Impact Unless Mitigation Incorporated" may be checked and a Mitigated Negative Declaration may be prepared. Rev. 11/17/08 EIA 08-01 LA GOLONDRINA & LA COSTA MEADOWS SEWER EXTENSIONS • An EIR must be prepared if "Potentially Significant Impact" is checked, and including but not limited to the following circumstances: (1) the potentially significant adverse effect has not been discussed or mitigated in an earlier EIR pursuant to applicable standards, and the developer does not agree to mitigation measures that reduce the adverse impact to less than significant; (2) a "Statement of Overriding Considerations" for the significant adverse impact has not been made pursuant to an earlier EIR; (3) proposed mitigation measures do not reduce the adverse impact to less than significant; or (4) through the EIA-Initial Study analysis it is not possible to determine the level of significance for a potentially adverse effect, or determine the effectiveness of a mitigation measure in reducing a potentially significant effect to below a level of significance. A discussion of potential impacts and the proposed mitigation measures appears after each related set of questions. Particular attention should be given to discussing mitigation for impacts, which would otherwise be determined significant. Rev. 11/17/08 EIA 08-01 LA GOLONDRINA & LA COSTA MEADOWS SEWER EXTENSIONS Potentially Significant Impact Potentially Significant Unless Mitigation Incorporated Less Than Significant No Impact Impact I. AESTHETICS - Would the project: a) Have a substantial adverse effect on a scenic vista? b) Substantially damage scenic resources, including but not limited to, trees, rock outcroppings, and historic buildings within a State scenic highway? c) Substantially degrade the existing visual character or quality of the site and its surroundings? d) Create a new source of substantial light and glare, which would adversely affect day or nighttime views in the area? a) - d) No Impact. The project includes a wastewater service area boundary adjustment and the construction of two underground gravity flow sewer pipeline segments, whichxwill allow for the removal of two temporary above ground sewer lift stations. No above ground structures are proposed. There will be minor and short term temporary impacts during construction, which would include trenching equipment, staging areas, and HDD drill equipment. However, the removal of the two existing above ground sewer lift stations will improve the aesthetics of the two parcels they are located on within a residential area and adjacent to open space preserves. Therefore, the project would not a) adversely affect a scenic vista, b) substantially damage scenic resources, c) degrade the existing visual character of any site, or d) create a new source of substantial light and glare, which would adversely affect day or nighttime views in the area. As such, the proposed project will not have any adverse effects on aesthetics. No impact is identified. II. AGRICULTURAL RESOURCES - (In determining whether impacts to agricultural resources are significant environmental effects, lead agencies may refer to the California Agricultural Land Evaluation and Site Assessment Model-1997 prepared by the California Department of Conservation as an optional model to use in assessing impacts on agriculture and farmland.) Would the project: a) Convert Prime Farmland, Unique Farmland, or Farmland of Statewide Importance (Farmland), as shown on the maps prepared pursuant to the Farmland Mapping and Monitoring Program of the California Resources Agency, to non-agricultural use? b) Conflict with existing zoning for agricultural use, or a Williamson Act contract? Potentially Significant Impact Potentially Significant Unless Mitigation Incorporated Less Than Significant No Impact Impact Rev. 11/17/08 EIA 08-01 LA GOLONDRINA & LA COSTA MEADOWS SEWER EXTENSIONS Potentially Significant Impact Potentially Significant Unless Mitigation Incorporated Less Than Significant Impact No' Impact c) Involve other changes in the existing environment, which, due to their location or nature, could result in conversion of Farmland to non-agricultural use? a) - c) No Impact. Both sewer extension pipelines will be constructed partially through the City's Habitat Management Plan Hardline Preserve Areas (HPA) and within the public right-of-way. No agricultural uses occur within the project area or in the immediate vicinity, nor are any agricultural land uses planned in the area. Therefore, the project would not a) convert farmland to a non-agricultural use, b) conflict with existing zoning for agricultural uses, or a Williamson Act contract, or c) involve other changes in the existing environment, which would result in conversion of farmland to a non-agricultural use. As such, the proposed project will not have any adverse effects on agricultural resources. No impact is identified. Potentially Significant Impact Potentially Significant Unless Mitigation Incorporated Less Than Significant No Impact Impact III. AIR QUALITY - (Where available, the significance criteria established by the applicable air quality management or air pollution control district may be relied upon to make the following determinations.) Would the project: a) Conflict with or obstruct implementation of the applicable air quality plan? b) Violate any air quality standard or contribute substantially to an existing or projected air quality violation? c) Result in a cumulatively considerable net increase of any criteria pollutant for which the project region is in non-attainment under an applicable federal or state ambient air quality standard (including releasing emissions which exceed quantitative thresholds for ozone precursors)? d) Expose sensitive receptors to substantial pollutant concentrations? e) Create objectionable odors affecting a substantial number of people? a) No Impact. The project site is located in the San Diego Air Basin which is a state non-attainment area for ozone (O3) and for particulate matter less than or equal to 10 microns in diameter (PM10). The periodic violations of national Ambient Air Quality Standards (AAQS) in the San Diego Air Basin (SDAB), particularly for ozone in inland foothill areas, requires that a plan be developed outlining the pollution controls that will be undertaken to improve air quality. In San Diego County, this attainment planning process is embodied in the Regional Air Quality Strategies (RAQS) developed jointly by the Air Pollution Control District (APCD) and the San Diego Association of Governments (SANDAG). Rev. 11/17/08 EIA 08-01 LA GOLONDRINA & LA COSTA MEADOWS SEWER EXTENSIONS A Plan to meet the federal standard for ozone was developed in 1994 during the process of updating the 1991 state- mandated plan. This local plan was combined with plans from all other California non-attainment areas having serious ozone problems and used to create the California State Implementation Plan (SIP). The SIP was adopted by the Air Resources Board (ARB) after public hearings on November 9th through 10* in 1994, and was forwarded to the Environmental Protection Agency (EPA) for approval. After considerable analysis and debate, particularly regarding airsheds with the worst smog problems, EPA approved the SIP in mid-1996. The proposed project relates to the SIP and/or RAQS through the land use and growth assumptions that are incorporated into the air quality planning document. These growth assumptions are based on each city's and the County's general plan. If a proposed project is consistent with its applicable General Plan, then the project presumably has been anticipated with the regional air quality planning process. Such consistency would ensure that the project would not have an adverse regional air quality impact. Section 15125(B) of the State of California Environmental Quality Act (CEQA) Guidelines contains specific reference to the need to evaluate any inconsistencies between the proposed project and the applicable air quality management plan. Transportation Control Measures (TCMs) are part of the RAQS. The RAQS and TCM plan set forth the steps needed to accomplish attainment of state and federal ambient air quality standards. The California Air Resources Board provides criteria for determining whether a project conforms with the RAQS which include the following: • Is a regional air quality plan being implemented in the project area? • Is the project consistent with the growth assumptions in the regional air quality-plan? The project area is located in the San Diego Air Basin, and as such, is located in an area where a RAQS is being implemented. The project is consistent with the regional air quality plan and will in no way conflict or obstruct implementation of the regional plan. No impact is assessed. b) Less Than Significant Impact. The closest air quality monitoring station to the project site is at Camp Pendleton. Data available for this monitoring site from 2000 through December 2004 indicate that the most recent air quality violations recorded were for the state one hour standard for ozone (a total of 10 days during the 5-year period). No other violations of any air quality standards have been recorded during the 5-year time period. The project would involve minimal short-term emissions associated with trenching, drilling, construction of the sewer pipelines, and removal of the two existing above grade sewer lift stations. Such emissions would be minimized through standard construction measures such as the use of properly tuned equipment and watering the site for dust control. Long-term emissions associated with travel to and from the project site to maintain or repair the sewer pipelines will be minimal. Although air pollutant emissions would be associated with the project, they would neither result in the violation of any air quality standard (comprising only an incremental contribution to overall air basin quality readings), nor contribute substantially to an existing or projected air quality violation. Any impact is assessed as less than significant. c) Less Than Significant Impact. The air basin is currently in a state non-attainment zone for ozone and suspended fine particulates. The proposed project would represent a contribution to a cumulatively considerable potential net increase in emissions throughout the air basin. As described above, however, emissions associated with the proposed project would be minimal. Given the limited emissions potentially associated with the proposed project, air quality would be essentially the same whether or not the proposed project is implemented. According to the CEQA Guidelines Section 15130(a)(4), the proposed project's contribution to the cumulative impact is considered de minimus. Any impact is assessed as less than significant. d) No impact. As noted above, the proposed would not result in substantial pollutant emissions or concentrations. In addition, there are no sensitive receptors (e.g., schools or hospitals) located in the vicinity of the project. No impact is assessed. e) No Impact. The construction of the proposed project could generate fumes from the operation of construction equipment, which may be considered objectionable by some people. Such exposure would be short-term or transient. In addition, the number of people exposed to such transient impacts is not considered substantial. No impact is assessed. 10 Rev. 11/17/08 EIA 08-01 LA GOLONDRINA & LA COSTA MEADOWS SEWER EXTENSIONS Potentially Significant Impact Potentially Significant Unless Mitigation Incorporated Less Than Significant No Impact Impact IV. BIOLOGICAL RESOURCES - Would the project: a) Have a substantial adverse effect, either directly or through habitat modifications, on any species identified as a candidate, sensitive, or special status species in local or regional plans, policies, or regulations, or by California Department of Fish and Game or U.S. Fish and Wildlife Service? b) Have a substantial adverse effect on any riparian, aquatic or wetland habitat or other sensitive natural community identified in local or regional plans, policies, or regulations or by California Department of Fish and Game or U.S. Fish and Wildlife Service? c) Have a substantial adverse effect on federally protected wetlands as defined by Section 404 of the Clean Water Act (including but not limited to marsh, vernal pool, coastal, etc.) through direct removal, filling, hydrological interruption, or other means? d) Interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impede the use of native wildlife nursery sites? e) Conflict with any local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance? f) Conflict with the provisions of an adopted Habitat Conservation Plan, Natural Community Conservation Plan, or other approved local, regional, or state habitat conservation plan? a) - c), e), f) No Impact. The project includes a wastewater service area boundary adjustment and the construction of two underground gravity flow sewer pipeline segments which will allow for the removal of two temporary above ground sewer lift stations. The pipeline segments include the construction of approximately 1,500 lineal feet of 8- and 10-inch diameter pipeline by traditional open trench method within the street right-of-way, and 1,300 lineal feet of 10-inch diameter pipeline by HDD method, which is a trenchless technology. Both sewer extension pipelines will be constructed partially through the City's Habitat Management Plan Hardline Conservation Areas (HCA). However, the areas through the HCA will be constructed using the HDD method, which is a trenchless method and avoids direct removal of sensitive vegetation. The HDD method does require drill pits to be located at each end of the underground pipeline to allow room for the drill and pipe to be installed. However, the drill pits will be located in ornamental vegetation or in disturbed areas. The sewer lift stations are both located in developed (paved) access areas, thus their removal will not result in impacts to existing vegetation. According to the Biological Resources Technical Report dated September 2008, and prepared by Dudek, "Implementation of the proposed project would not result in significant direct impacts to native vegetation communities, 11 Rev. 11/17/08 EIA 08-01 LA GOLONDRINA & LA COSTA MEADOWS SEWER EXTENSIONS including coastal sage scrub, coastal and valley freshwater marsh, or chaparral." As mentioned previously, the project is using the HDD method through the HCA and, therefore, the project will not a) have a substantial adverse effect, either directly or through habitat modifications, on any species identified as a candidate, sensitive, or special status species in local or regional plans, policies, or regulations, b) have a substantial adverse effect on any riparian, aquatic or wetland habitat or other sensitive natural communities, c) have a substantial adverse effect on federally protected wetlands, e) conflict with any local policies or ordinances protecting biological resources, or f) conflict with the provisions of an adopted Habitat Conservation Plan or Natural Community Conservation Plan. In addition, the spoils will be protected from erosion in compliance with the City's National Pollutant Discharge Elimination System Permit (NPDES) and approved Best Management Practices (BMPs). No impact is identified. d) Potentially Significant Unless Mitigation Incorporated. The pipeline segments include the construction of approximately 1,500 lineal feet of 8- and 10-inch diameter pipeline by traditional open trench method within the street right-of-way, and 1,300 lineal feet of 10-inch diameter pipeline by HDD method, which is a trenchless technology. Both sewer extension pipelines will be constructed partially through the City's Habitat Management Plan Hardline Conservation Areas (HCA). Although, the areas through the HCA will be constructed using the HDD method, that is a trenchless method and avoids direct removal of sensitive vegetation. As stated above, the HDD method does require drill pits to be located at each end of the underground pipeline to allow room for the drill and pipe to be installed. However, the drill pits will be located in ornamental vegetation or in disturbed areas. The project is underground and will not result in impacts to biological resources, including the movement of any native resident or migratory wildlife species, or wildlife corridors; however, temporary construction noise and vibration could result in temporary impacts on nesting or breeding birds. According to the Biological Resources Technical Report dated September 2008, and prepared by Dudek, "the project may result in significant indirect impacts to nesting bird species, including the coastal California gnatcatcher, from noise and ground vibration and to native vegetation communities, including coastal and valley freshwater marsh, from dust or runoff." The spoils will be protected from erosion in compliance with the City's National Pollutant Discharge Elimination System Permit (NPDES) and approved Best Management Practices (BMPs). With implementation of the following mitigation measures, the project will not result in significant impacts to any biological resources. Any impact is assessed as less than significant. Mitigation Measures for Sensitive Wildlife Species BIO-1 If the construction activities occur during the nesting bird season (February 15 through September 15), the following measures must be taken (per Section 8.1.3-Species-Specific Mitigation from the Guidelines for Biological Studies [Technology Associates 2008]): • A qualified biologist will conduct a focused species gnatcatcher survey in appropriate habitat within and surrounding the project area. The surveys will consist of three visits, one week apart; the last of these will be conducted no more than three days prior to construction. • Surveys will also be conducted by a qualified biologist in appropriate habitat for nesting raptors and migratory birds (including, but not limited to the least Bell's vireo) and within an additional 500-ft buffer within three days of construction. • The USFWS will be notified immediately of any federally listed species that are located during pre- construction surveys. 12 Rev. 11/17/08 EIA 08-01 LA GOLONDRINA & LA COSTA MEADOWS SEWER EXTENSIONS • If nests of listed birds, migratory birds, raptors, or other sensitive species are located, they will be fenced with a protective buffer of at least 500 feet from active nests of raptors and listed species, and 300 feet from other sensitive bird species. All construction activity will be prohibited within this area. • During the breeding season, construction noise will be measured regularly to maintain a threshold at or below 60 dBA hourly Leq within 500 feet of breeding habitat occupied by listed species. If noise levels supersede the threshold, the construction array will be changed or noise attenuation measures will be implemented. In order to comply with the HMP guidelines, there will be a no net loss of native vegetation communities within the Hardline Conservation Areas. Mitigation Measures for Sensitive Vegetation Communities BIO-2 A biological monitor shall be present during the construction process in order to review the limits of work and Best Management Practices (BMPs) prior to commencement of construction and to periodically check the compliance of environmental regulations. BIO-3 BMPs should be applied that result in the open-trench area, staging area, and drill rig to specifically avoid indirect impacts to the coastal and valley freshwater marsh. These should also apply to minimizing or avoiding disturbance to coastal sage scrub, chaparral, southern willow scrub, and the mapped locations of California adolphia (Adolphia californica). Such BMPs may include installation of silt fencing and dust control measures. BIO-4 In order to avoid impacts to vegetation communities from the possibility of an escape of the bentonite slurry into the environment (frac-out), the project contractor will submit an Emergency Frac- Out Containment Plan to the Engineering Department. The plan will outline actions to be taken in the event a frac-out occurs. The plan shall include a requirement to immediately notify the biological monitor and for the monitor to conduct an assessment of biological impacts. V. CULTURAL RESOURCES - Would the project: a) Cause a substantial adverse change in the significance of a historical resource as defined in §15064.5? b) Cause a substantial adverse change in the signifi- cance of an archeological resource pursuant to §15064.5? c) Directly or indirectly destroy a unique pale ontological resource or site or unique geologic feature? d) Disturb any human remains, including those interred outside of formal cemeteries? Potentially Significant Impact Potentially Significant Unless Mitigation Incorporated Less Than Significant No Impact Impact a) - d) No Impact. The project includes a wastewater service area boundary adjustment and the construction of two underground gravity flow sewer pipeline segments which will allow for the removal of two temporary above ground sewer lift stations. These sewer lift stations are not considered historical 13 Rev. 11/17/08 EIA 08-01 LA GOLONDRINA & LA COSTA MEADOWS SEWER EXTENSIONS resources. According to the archeological map and reports the City of Carlsbad has on file there are no known archaeologically sensitive areas in the vicinity of the proposed project. Furthermore, part of the project site has been previously disturbed by the construction of paved roads and other utilities within the street right-of-way. However, in the event that human remains are found, the contractor would comply with the procedures and requirements set forth in the California Health and Safety Code Section 7050.5 and Public resources Code Section 5097.98. The County Coroner and the Native American Heritage Commission would be notified and, in turn, would notify those persons believed to be most likely descended from the deceased for appropriate disposition of the remains. As such, the proposed project will not have any adverse effects on cultural resources. No impact is identified. VI. GEOLOGY AND SOILS - Would the project: a) Expose people or structures to potential substantial adverse effects, including the risk of loss, injury or death involving: i. Rupture of a known earthquake fault, as delineated on the most recent Alquist-Priolo Earthquake Fault Zoning Map issued by the State Geologist for the area or based on other substantial evidence of a known fault? Refer to Division of Mines and Geology Special Publication 42. ii. Strong seismic ground shaking? iii. Seismic-related ground failure, including liquefaction? iv. Landslides? b) Result in substantial soil erosion or the loss of topsoil? c) Be located on a geologic unit or soil that is unstable, or that would become unstable as a result of the project, and potentially result in on- or off-site landslide, lateral spreading, subsidence, liquefaction, or collapse? d) Be located on expansive soils, as defined in Section 1802.3.2 of the California Building Code (2007), creating substantial risks to life or property? e) Have soils incapable of adequately -supporting the use of septic tanks or alternative wastewater disposal systems where sewers are not available for the disposal of wastewater? Potentially Significant Impact Potentially Significant Unless Mitigation Incorporated Less Than Significant No Impact Impact 14 Rev. 11/17/08 EIA 08-01 LA GOLONDRINA & LA COSTA MEADOWS SEWER EXTENSIONS ai) - aiv) No Impact. The project would not expose people or structures to potential substantial adverse effects from the rupture of a known earthquake fault, strong seismic ground shaking, seismic-related ground failure, liquefaction, or landslides. There are no Alquist-Priolo Earthquake Fault zones within the City of Carlsbad and there is no other evidence of active or potentially active faults within the City. However, there are several active faults throughout Southern California, and these potential earthquakes could affect Carlsbad. Landslides are also a potential threat in parts of the City. All development proposals in Carlsbad are subject to requirements such as the California Building Code earthquake construction standards and soil remediation that when necessary ensure potential adverse effects are not significant. As such, the proposed project will not have any adverse effects on geological resources. No impact is identified. b) No Impact. The project includes a wastewater service area boundary adjustment and the construction of two underground gravity flow sewer pipeline segments which will allow for the removal of two temporary above ground sewer lift stations. No above ground structures are proposed as part of the project and the two existing above ground sewer lift stations will be removed. The project is subject to the City's National Pollutant Discharge Elimination System Permit (NPDES) and Best Management Practices (BMPs). The project would not result in substantial soil erosion or the loss of topsoil. As such, the proposed project will not have any adverse effects on soil erosion. No impact is identified. c) - e) No Impact. No above ground structures are proposed as part of the project and the two existing above ground sewer lift stations will be removed. According to the Biological Resources Technical Report dated September 2008, and prepared by Dudek, the Soil Survey of San Diego Area, California, Park I, Sheet 22 (Bowman 1973) was consulted and one soil type was mapped within both of the study areas: Huerhuero loam (HrE2). The Huerhuero Series consists of moderately well drained loams that have clay subsoil. No other soil types were mapped as occurring in the study area. Therefore, the soil type is not considered expansive. The project does not propose a septic tank or alternative wastewater disposal system. In addition, the project is subject to the City's National Pollutant Discharge Elimination System Permit (NPDES) and Best Management Practices (BMPs). As such, the proposed project will not have any adverse effects on geology or soils. No impact is identified. VII. HAZARDS AND HAZARDOUS MATERIALS - Would the project: a) Create a significant hazard to the public or the environment through the routine transport, use, or disposal of hazardous materials? b) Create a significant hazard to the public or environment through reasonably foreseeable upset and accident conditions involving the release of hazardous materials into the environment? c) Emit hazardous emissions or handle hazardous or acutely hazardous materials, substances, or waste within one-quarter mile of an existing or proposed school? Potentially Significant Impact Potentially Significant Unless Mitigation Incorporated Less Than Significant No Impact Impact 15 Rev. 11/17/08 El A 08-01 LA GOLONDRINA & LA COSTA MEADOWS SEWER EXTENSIONS d) Be located on a site which is included on a list of hazardous materials sites compiled pursuant to Government Code Section 65962.5 and, as a result, would it create a significant hazard to the public or environment? e) For a project within an airport land use plan, or where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project result in a safety hazard for people residing or working in the project area? f) For a project within the vicinity of a private airstrip, would the project result in a safety hazard for people residing or working in the project area? Potentially Significant Impact Potentially Significant Unless Mitigation Incorporated Less Than Significant Impact No Impact g) Impair implementation of or physically interfere with an adopted emergency response plan or emergency evacuation plan? h) Expose people or structures to a significant risk of loss, injury or death involving wildland fires, including where wildlands are adjacent to urbanized areas or where residences are intermixed with wildlands? a) - d) No Impact. The project includes a wastewater service area boundary adjustment and the construction of two underground gravity flow sewer pipeline segments which will allow for the removal of two temporary above ground sewer lift stations. No above ground structures are proposed as part of the project and the two existing above ground sewer lift stations will be removed. No use of hazardous cleaning products on the site is expected to occur during the construction or permanent use phases. The Bentonite slurry is an absorbent aluminum phyllosilicate, generally impure clay consisting mostly of montmorillonite. Bentonite usually forms from weathering of volcanic ash, most often in the presence of water. All transport, handling, use, and disposal of any construction substances, including Bentonite, would comply with all federal, state, and local laws regulating the management and use of such materials. As such, the proposed project will not have any adverse effects on hazardous materials or create a hazardous condition. No impact is identified. e) & 1) No Impact. The project is located approximately two miles southeast of the McClellan-Palomar Airport. However, the project site is not located within the Flight Activity Zone or the Airport Influence Area as depicted in the San Diego County Regional Airport Authority Airport Land Use Compatibility Plan (ALUCP) for the McClellan-Palomar Airport, dated October 4, 2004. As such, the proposed project will not have any adverse effects on hazardous materials or create a hazardous condition near an airport. No impact is identified. g) No Impact. No above ground structures are proposed as part of the project and the two existing above ground sewer lift stations will be removed. The project would not interfere with the implementation of an adopted emergency response or evacuation plan. A note will be added to the construction plan to require the contractor to provide a Traffic Control Plan for review and approval by the City Engineer. All roads 16 Rev. 11/17/08 EIA 08-01 LA GOLONDRINA & LA COSTA MEADOWS SEWER EXTENSIONS will remain open to through traffic during construction of the project within the street right-of-way. Equipment and staging areas will also be shown on the construction plans. As such, the proposed project will not have any adverse effects on emergency responses or plans. No impact is identified. h) No Impact. No above ground structures are proposed as part of the project and the two existing above ground sewer lift stations will be removed. A proportion of the work will be within the street right-of-way and the other portion will be through open space. The project would not expose people or structures to a significant risk from wildland fires. As such, the proposed project will not have any adverse effects on emergency responses or plans. No impact is identified. VIII. HYDROLOGY AND WATER QUALITY - Would the project: a) Violate any water quality standards or waste discharge requirements? b) Substantially deplete groundwater supplies or interfere substantially with ground water recharge such that there would be a net deficit in aquifer volume or a lowering of the local ground water table level (i.e., the production rate of pre-existing nearby wells would drop to a level which would not support existing land uses or planned uses for which permits have been granted)? c) Substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river, in a manner, which would result in substantial erosion or siltation on- or off- site? d) Substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river, or substantially increase the flow rate or amount (volume) of surface runoff in a manner, which would result in flooding on- or off- site? e) Create or contribute runoff water, which would exceed the capacity of existing or planned stormwater drainage systems or provide substantial additional sources of polluted runoff? f) Otherwise substantially degrade water quality? g) Place housing within a 100-year flood hazard area as mapped on a Federal Flood Hazard Boundary or Flood Insurance Rate Map or other flood delineation map? Potentially Significant Impact Potentially Significant Unless Mitigation Incorporated Less Than Significant Impact No Impact 17 Rev. 11/17/08 EIA 08-01 LA GOLONDRINA & LA COSTA MEADOWS SEWER EXTENSIONS h) Place within 100-year flood hazard area structures, which would impede or redirect flood flows? i) Expose people or structures to a significant risk of loss, injury or death involving flooding, including flooding as a result of the failure of a levee or dam? j) Inundation by seiche, tsunami, or mudflow? ; Potentially Significant Impact Potentially Significant Unless Mitigation Incorporated Less Than Significant No Impact Impact k) Increase erosion (sediment) into receiving surface waters. 1) Increase pollutant discharges (e.g., heavy metals, pathogens, petroleum derivatives, synthetic organics, nutrients, oxygen-demanding substances and trash) into receiving surface waters or other alteration of receiving surface water quality (e.g. temperature, dissolved oxygen or turbidity? m) Change receiving water quality (marine, fresh or wetland waters) during or following construction? n) Increase any pollutant to an already impaired water body as listed on the Clean Water Act Section 303(d) list? o) Increase impervious surfaces and associated runoff? p) Impact aquatic, wetland, or riparian habitat? q) Result in the exceedance of applicable surface or groundwater receiving water quality objectives or degradation of beneficial uses? a) - f) No Impact. The project includes a wastewater service area boundary adjustment and the construction of two underground gravity flow sewer pipeline segments which will allow for the removal of two temporary above ground sewer lift stations. The pipeline segments include the construction of approximately 1,500 lineal feet of 8- and 10-inch diameter pipeline by traditional open trench method within the street right-of-way, and 1,300 lineal feet of 10-inch diameter pipeline by HDD method, which is a trenchless technology. No above ground structures are proposed as part of the project and the two existing above ground sewer lift stations will be removed. In addition, the project is subject to the City's National Pollutant Discharge Elimination System Permit (NPDES). In addition, the contractor shall implement Best Management Practices (BMPs), which will be shown on the construction plans. The contractor will ensure no water quality violations due to stockpiling of spoils during trenching operations. Therefore, the project would not conflict with any water quality standards, impact groundwater supplies/quality, alter any drainage pattern, impact the capacity of existing or planned stormwater 18 Rev. 11/17/08 EIA 08-01 LA GOLONDRINA & LA COSTA MEADOWS SEWER EXTENSIONS drainage systems, or result in the degradation of water quality. As such, the proposed project will not have any adverse effects on hydrology or water quality. No impact is identified. g) - j) No Impact. The project includes a wastewater service area boundary adjustment and the construction of two underground gravity flow sewer pipeline segments which will allow for the removal of two temporary above ground sewer lift stations. No above ground structures are proposed as part of the project and the two existing above ground sewer lift stations will be removed. According to the Federal Emergency Management Agency (FEMA) Flood Insurance Rate Map, San Diego County, California, Panel Number 1032 and Number 1051, respectively, the project is not within a 100-year flood hazard area. In addition, according to the City of Carlsbad's Final Master Environmental Impact Repot for the General Plan Update, dated March 1994, Map 5.10.1-2 the project site is not located within a dam failure inundation, a tsunami, or a seiche area. As such, the proposed project will not have any adverse effects on exposing people to flood hazards. No impact is identified. k) - q) No Impact. The project includes a wastewater service area boundary adjustment and the construction of two underground gravity flow sewer pipeline segments which will allow for the removal of two temporary above ground sewer lift stations. No above ground structures are proposed as part of the project and the two existing above ground sewer lift stations will be removed. The project will not increase impervious surface, erosion, pollutant discharges, or decrease water quality. In addition, the project is subject to the City's NPDES as well as the implementation of BMPs. Construction drawings shall show all BMPs on the plan. As such, the proposed project will not have any adverse effects on increasing erosion or pollutant discharges. No impact is identified. Less Than Significant No Impact Impact IX. LAND USE AND PLANNING - Would the project: a) Physically divide an established community? b) Conflict with any applicable land use plan, policy, or regulation of an agency with jurisdiction over the project (including but not limited to the general plan, specific plan, local coastal program, or zoning ordinance) adopted for the purpose of avoiding or mitigating an environmental effect? c) Conflict with any applicable habitat conservation plan or natural community conservation plan? a) No Impact. The project includes a wastewater service area boundary adjustment and the construction of two underground gravity flow sewer pipeline segments which will allow for the removal of two temporary above ground sewer lift stations. No above ground structures are proposed as part of the project and the two existing above ground sewer lift stations will be removed. All work will be performed within the existing open space preserve and within existing street right-of-ways. As such, the proposed project will not have any adverse effects on an established community. No impact is identified. b) No Impact. The project includes a wastewater service area boundary adjustment and the construction of two underground gravity flow sewer pipeline segments which will allow for the removal of two temporary above ground sewer lift stations. No above ground structures are proposed as part of the project and the two existing above ground sewer lift stations will be removed. The project area has a General Plan designation of Open Space (OS), Residential Low-Medium (RLM) housing density, Potentially Significant Impact Potentially Significant Unless Mitigation Incorporated 19 Rev. 11/17/08 EIA 08-01 LA GOLONDRINA & LA COSTA MEADOWS SEWER EXTENSIONS Secondary Arterial, and Undesignated Street Right-of-Way, and a Zoning designation of Planned Community (P-C), One-Family Residential (R-l), Secondary Arterial, and Other Roadway. As mentioned previously, there will be no above grade structures and the project is not located within the Coastal Zone. As such, the proposed project will not have any adverse effects on land use and planning. No impact is identified. c) Less Than Significant Impact. The project includes a wastewater service area boundary adjustment and the construction of two underground gravity .flow sewer pipeline segments which will allow for the removal of two temporary above ground sewer lift stations. No above ground structures are proposed as part of the project and the two existing above ground sewer lift stations will be removed. As identified in the City's adopted Habitat Management Plan (HMP), the project site is located within a Hardline Conservation Area (HCA); however, the portion of sewer extension pipelines that will be constructed through the HCA will be constructed using the Horizontal Directional Drilling (HDD) method, which is a trenchless method and avoids direct removal of sensitive vegetation. The project is underground and will not result in impacts to biological resources. However, as stated in Section IV, Biological Resources item d), the proposed project will not result in impacts to biological resources, including the movement of any native resident or migratory wildlife species, or wildlife corridors; however, temporary construction noise and vibration could result in temporary impacts on nesting or breeding birds. The project will comply with the mitigation measures listed in this document-and listed in the Mitigation, Monitoring, and Reporting Program (MMRP). Therefore, the project would be consistent w}th the City of Carlsbad's adopted HMP. Impacts would be less than significant. Potentially Significant Impact Potentially Significant Unless Mitigation Incorporated Less Than Significant No Impact Impact X. MINERAL RESOURCES - Would the project: a) Result in the loss of availability of a known mineral resource that would be of future value to the region and the residents of the State? b) Result in the loss of availability of a locally important mineral resource recovery site delineated on a local general plan, specific plan, or other land use plan? a) & b) No Impact. The project includes a wastewater service area boundary adjustment and the construction of two underground gravity flow sewer pipeline segments which will allow for the removal of two temporary above ground sewer lift stations. No above ground structures are proposed as part of the project and the two existing above ground sewer lift stations will be removed. The General Plan's Land Use Map does not identify any areas within Carlsbad for mineral deposits or mineral resource recovery sites. As such, the proposed action will not have any adverse effects on mineral resources. No impact is identified. 20 Rev. 11/17/08 EIA 08-01 LA GOLONDRINA & LA COSTA MEADOWS SEWER EXTENSIONS Potentially Significant Impact Potentially Significant Unless Mitigation Incorporated Less Than Significant No Impact Impact IEI IEI XI. NOISE - Would the project result in: a) Exposure of persons to or generation of noise levels in excess of standards established in the local general plan or noise ordinance or applicable standards of other agencies? b) Exposure of persons to or generation of excessive groundbourne vibration or groundbourne noise levels? c) A substantial permanent increase in ambient noise levels in the project vicinity above levels existing without the project? d) A substantial temporary or periodic increase in ambient noise levels in the project vicinity above levels existing without the project? e) For a project located within an airport land use plan or, where such a plan has not been adopted, within 2 miles of a public airport or public use airport, would the project expose people residing or working in the project area to excessive noise levels? f) For a project within the vicinity of a private airstrip, would the project expose people residing or working in the project area to excessive noise levels? a) - d) Less Than Significant Impact. The proposed project would result in a temporary noise increase during construction activities (i.e. HDD & trenching machinery). The use of heavy equipment would temporarily increase the noise levels and would result in temporary noise impacts to the adjacent areas. The HDD method could also expose persons to excessive groundbourne vibration or groundbourne noise levels. The proposed construction activities would be conducted in compliance with the City of Carlsbad Municipal Code Chapter 8.48, which preclude construction after sunset* on any day, before seven (7) a.m. Monday through Friday, before eight (8) a.m. on Saturday, and all day on Sunday and specified holidays. The Noise Ordinance does not set a defined noise level standard for construction activities, but simply limits the hours of construction. The proposed construction activities, and the noise generated from these activities, are short-term in nature. No noise sources are proposed with the project. Therefore, the impact would be less than significant. e) & f) No Impact. The project includes a wastewater service area boundary adjustment and the construction of two underground gravity flow sewer pipeline segments which will allow for the removal of two temporary above ground sewer lift stations. No above ground structures are proposed as part of the project and the two existing above ground sewer lift stations will be removed. The project is located approximately two miles southeast of the McClellan-Palomar Airport. However, the project site is not located within the Flight Activity Zone or the Airport Influence Area as depicted in the San Diego County Regional Airport Authority Airport Land Use Compatibility Plan (ALUCP) for the McClellan-Palomar Airport, dated October 4, 2004. Therefore, the project would not result in exposing people to excessive 21 Rev. 11/17/08 EIA 08-01 LA GOLONDRINA & LA COSTA MEADOWS SEWER EXTENSIONS noise levels associated with an airport. As such, the proposed project will not have any adverse effects on exposing people within the vicinity of an airport to an increase in noise levels. No impact is identified. Potentially Significant Impact Potentially Significant Unless Mitigation Incorporated Less Than Significant No Impact Impact XII. POPULATION AND HOUSING - Would the project: a) Induce substantial growth in an area either directly (for example, by proposing new homes and businesses) or indirectly (for example, through extension of roads or other infrastructure)? b) Displace substantial numbers of existing housing, necessitating the construction of replacement housing elsewhere? c) Displace substantial numbers of people, necessitating the construction of replacement housing elsewhere? a) - c) No Impact. The project includes a wastewater service area boundary adjustment and the construction of two underground gravity flow sewer pipeline segments which will allow for the removal of two temporary above ground sewer lift stations. No above ground structures are proposed as part of the project and the two existing above ground sewer lift stations will be removed. The proposed sewer line installation is part of a program to eliminate sewer pump stations and convert to gravity flow where feasible. All facilities are sized to accommodate the amount of growth indicated and limited by the City's Growth Management Program; therefore, the proposed sewer line does not have any direct or indirect growth-inducing impacts. In addition, the project would not displace substantial numbers of existing housing or people, necessitating the construction of replacement housing elsewhere, because the project is within an open space preserve and street right-of-way. As such, the proposed project will not have any adverse effects on population and housing. No impact is identified. Potentially Significant Potentially Unless Significant Mitigation Impact Incorporated Less Than Significant No Impact Impact XIII. PUBLIC SERVICES a) Would the project result in substantial adverse physical impacts associated with the provision of new or physically altered government facilities, a need for new or physically altered government facilities, the construction of which could cause significant environmental impacts, in order to maintain acceptable service ratios, response times, or other performance objectives for any of the public services: i) Fire protection? ii) Police protection? 22 Rev. 11/17/08 EIA 08-01 LA GOLONDRINA & LA COSTA MEADOWS SEWER EXTENSIONS iii) Schools? iv) Parks? v) Other public facilities? Potentially Significant Impact Potentially Significant Unless Mitigation Incorporated Less Than Significant No Impact Impact ai) - av) No Impact. The project includes a wastewater service area boundary adjustment and the construction of two underground gravity flow sewer pipeline segments which will allow for the removal of two temporary above ground sewer lift stations. No above ground structures are proposed as part of the project and the two existing above ground sewer lift stations will be removed. The project does not involve any construction or development that would require provisions of public services such as fire or police protection, schools, parks, or other public facilities. The sewer line extensions are proposed to accommodate existing and planned future growth and, therefore, would not result in substantial adverse physical impacts associated with the provision of new or physically altered government facilities, or in order to maintain acceptable service ratios, response times, or other performance objectives for any public service. As such, the proposed project will not have any adverse effects on pubjic services. No impact is identified. Less Than Significant No Impact Impact XIV. RECREATION Potentially Significant Impact Potentially Significant Unless Mitigation Incorporated a) Would the project increase the use of existing neighborhood and regional parks or other recreational facilities such that substantial physical deterioration of the facility would occur or be accelerated? b) Does the project include recreational facilities or require the construction or expansion of recreational facilities, which might have an adverse physical effect on the environment? a) & b) No Impact. The project includes a wastewater service area boundary adjustment and the construction of two underground gravity flow sewer pipeline segments which will allow for the removal of two temporary above ground sewer lift stations. No above ground structures are proposed as part of the project and the two existing above ground sewer lift stations will be removed. Since the proposed sewer line extensions do not increase the capacity of growth beyond that allowed by the City's Growth Management Program, the project will not increase the use of existing neighborhood and regional parks, such that substantial physical deterioration of the facility would occur or be accelerated, or construct recreational facilities, which might have an adverse physical effect on the environment. As such, the proposed project will not have any adverse effects on recreation. No impact is identified. 23 Rev. 11/17/08 EIA 08-01 LA GOLONDRINA & LA COSTA MEADOWS SEWER EXTENSIONS XV. TRANSPORTATION/TRAFFIC - Would the project. a) Cause an increase in traffic, which is substantial in relation to the existing traffic load and capacity of the street system (i.e., result in a substantial increase in either the number of vehicle trips, the volume to capacity ratio on roads, or congestion at intersections)? b) Exceed, either individually or cumulatively, a level of service standard established by the county congestion management agency for designated roads or highways? c) Result in a change in air traffic patterns, including either an increase in traffic levels or a change in location that results in substantial safety risks? Potentially Significant Impact Potentially Significant Unless Mitigation Incorporated Less Than Significant No Impact Impact d) Substantially increase hazards due to a design feature (e.g., sharp curves or dangerous intersections) or incompatible uses (e.g., farm equipment)? e) Result in inadequate emergency access? f) Result in insufficient parking capacity? g) Conflict with adopted policies, plans, or programs supporting alternative transportation (e.g., bus turn- outs, bicycle racks)? a) - g) No Impact. The project includes a wastewater service area boundary adjustment and the construction of two underground gravity flow sewer pipeline segments which will allow for the removal of two temporary above ground sewer lift stations. No above ground structures are proposed as part of the project and the two existing above ground sewer lift stations will be removed. The project will not generate traffic other than minor temporary traffic, lasting no longer than six months, during the construction period. The trenching will take place within El Fuerte Street right-of-way. Standard, approved traffic controls will be utilized during the construction so that traffic can continue to use the streets during the construction period. No long- term increase in traffic will result from the underground sewer extension project. In addition, the project will not exceed a level of service standard, change air traffic patterns, substantially increase road hazards, result in inadequate emergency access, result in insufficient parking capacity, or conflict with an adopted policy, plan or program supporting alternative transportation. As such, the proposed project will not have any adverse impacts on transportation or traffic. No impact is identified. 24 Rev. 11/17/08 EIA 08-01 LA GOLONDRINA & LA COSTA MEADOWS SEWER EXTENSIONS XVI. UTILITIES AND SERVICES SYSTEMS - Would the project: a) Exceed wastewater treatment requirements of the applicable Regional Water Quality Control Board? b) Require or result in the construction of new water or wastewater treatment facilities or expansion of existing facilities, the construction of which would cause significant environmental effects? c) Require or result in the construction of new storm water drainage facilities or expansion of existing facilities, the construction of which could cause significant environmental effects? d) Have sufficient water supplies available to serve the project from existing entitlements and resources, or are new or expanded entitlements needed? e) Result in a determination by the wastewater treatment provider, which serves or may serve the project that it has adequate capacity to serve the project's projected demand in addition to the provider's existing commitments? f) Be served by a landfill with sufficient permitted capacity to accommodate the project's solid waste disposal needs? Potentially Significant Impact Potentially Significant Unless Mitigation Incorporated Less Than Significant No Impact Impact Esl M g) Comply with federal, state, and local statutes and regulations related to solid waste? a) - g) No Impact. The project includes a wastewater service area boundary adjustment and the construction of two underground gravity flow sewer pipeline segmenta which will allow for the removal of two temporary above ground sewer lift stations. No above ground structures are proposed as part of the project and the two existing above ground sewer lift stations will be removed. No water or storm drain facilities are proposed or impacted by this project. The existing sewer pump stations are proposed to be removed and replaced with a gravity sewer system that ties into an existing sewer line on El Fuerte Street and Vermarine Court, respectively. The proposed gravity sewer is preferable to the pump station for both function and safety reasons. The installation of the sewer lines would not increase the capacity of the system to a level higher than anticipated by the City's Growth Management Program, and would not exceed wastewater treatment requirements, or result in the need for new water, wastewater or solid waste systems. As such, the proposed project will not have any adverse effects on utilities and service systems. No impact is identified. 25 Rev. 11/17/08 EIA 08-01 LA GOLONDRINA & LA COSTA MEADOWS SEWER EXTENSIONS Potentially Significant Impact Potentially Significant Unless Mitigation Incorporated Less Than Significant No Impact Impact XVII. MANDATORY FINDINGS OF SIGNIFICANCE a) Does the project have the potential to degrade the quality of the environment, substantially reduce the habitat of a fish or wildlife species, cause a fish or wildlife population to drop below self-sustaining levels, threaten to eliminate a plant or animal community, reduce the number or restrict the range of a rare or endangered plant or animal or eliminate important examples of the major periods of California history or prehistory? b) Does the project have impacts that are individually limited, but cumulatively considerable? ("Cumula- tively considerable" means that the incremental effects of a project are considerable when viewed in connection with the effects of past projects, the effects of other current projects, and the effects of probable future projects?) c) Does the project have environmental effects, which will cause the substantial adverse effects on human beings, either directly or indirectly? a) Potentially Significant Unless Mitigation Incorporated. Based on evaluation and discussions contained in this Initial Study and MND, the proposed project has limited potential to degrade the quality of the environment. The proposed project would not significantly affect the environment with the recommended mitigation measures incorporated into the project, particularly for sensitive wildlife species and sensitive vegetative communities. With implementation of the following mitigation measures, the project will not degrade the quality of the environment, substantially reduce the habitat of a fish or wildlife species, cause a fish or wildlife population to drop below self-sustaining levels, threaten to eliminate a plant or animal community, reduce the number or restrict the range of a rare or endangered plant or animal or eliminate important examples of the major periods of California history or prehistory. Any impact is assessed as less than significant. Mitigation Measures for Sensitive Wildlife Species BIO-1 If the construction activities occur during the nesting bird season (February 15 through September 15), the following measures must be taken (per Section 8.1.3-Species-Specific Mitigation from the Guidelines for Biological Studies [Technology Associates 2008]): • A qualified biologist will conduct a focused species gnatcatcher survey in appropriate habitat within and surrounding the project area. The surveys will consist of three visits, one week apart; the last of these will be conducted no more than three days prior to construction. • Surveys will also be conducted by a qualified biologist in appropriate habitat for nesting raptors and migratory birds (including, but not limited to the least Bell's vireo) and within an additional 500-ft buffer within three days of construction. 26 Rev. 11/17/08 EIA 08-01 LA GOLONDRJNA & LA COSTA MEADOWS SEWER EXTENSIONS • The USFWS will be notified immediately of any federally listed species that are located during pre- construction surveys. • If nests of listed birds, migratory birds, raptors, or other sensitive species are located, they will be fenced with a protective buffer of at least 500 feet from active nests of raptors and listed species, and 300 feet from other sensitive bird species. All construction activity will be prohibited within this area. • During the breeding season, construction noise will be measured regularly to maintain a threshold at or below 60 dBA hourly Leq within 500 feet of breeding habitat occupied by listed species. If noise levels supersede the threshold, the construction array will be changed or noise attenuation measures will be implemented. In order to comply with the HMP guidelines, there will be a no net loss of native vegetation communities within the Hardline Conservation Areas. Mitigation Measures for Sensitive Vegetation Communities BIO-2 A biological monitor shall be present during the construction process in order to review the limits of work and Best Management Practices (BMPs) prior to commencement of construction and to periodically check the compliance of environmental regulations. BIO-3 BMPs should be applied that result in the open-trench area, stagjng area, and drill rig to specifically avoid indirect impacts to the coastal and valley freshwater marsh. These should also apply to minimizing or avoiding disturbance to coastal sage scrub, chaparral, southern willow scrub, and the mapped locations of California adolphia (Adolphia californica). Such BMPs may include installation of silt fencing and dust control measures. BIO-4 hi order to avoid impacts to vegetation communities from the possibility of an escape of the bentonite slurry into the environment (frac-out), the project contractor will submit an Emergency Frac- Out Containment Plan to the Engineering Department. The plan will outline, actions to be taken in the event a frac-out occurs. The plan shall include a requirement to immediately notify the biological monitor and for the monitor to conduct an assessment of biological impacts. b) Less Than Significant Impact. Mitigation measures are provided to reduce the project's significant impact to biological resources. The mitigation measures and conditions of approval ensures the incremental impacts from development would not contribute to significant cumulative impacts. The City's HMP-was designed to mitigate cumulative biological impacts in the city. This project's conformance to this plan ensures that this project avoids the potential to contribute to a significant cumulative impact to biology. The proposed project would be consistent with ongoing sewer operations to provide gravity sewer pipelines to the surrounding area. The project's contribution to significant cumulative impacts would therefore be below a level of significance. c) No Impact. The proposed project would meet all existing standards established by federal, state, and local regulations. No substantial indirect or direct adverse effects would result from the project. No impact is identified. 27 Rev. 11/17/08 EIA 08-01 LA GOLONDRINA & LA COSTA MEADOWS SEWER EXTENSIONS XVIII. EARLIER ANALYSES Earlier analyses may be used where, pursuant to the tiering, program EIR, or other CEQA process, one or more effects have been adequately analyzed in an earlier EIR or negative declaration. Section 15063(c)(3)(D). In this case a discussion should identify the following on attached sheets: a) Earlier analyses used. Identify earlier analyses and state where they are available for review. b) Impacts adequately addressed. Identify which effects from the above checklist were within the scope of and adequately analyzed in an earlier document pursuant to applicable legal standards, and state whether such effects were addressed by mitigation measures based on the earlier analysis. c) Mitigation measures. For effects that are "Less Than Significant with Mitigation Incorporated," describe the mitigation measures, which were incorporated or refined from the earlier document and the extent to which they address site-specific conditions for the project. 28 Rev. 11/17/08 EIA 08-01 LA GOLONDRINA & LA COSTA MEADOWS SEWER EXTENSIONS EARLIER ANALYSIS USED AND SUPPORTING INFORMATION SOURCES The following documents were used in the analysis of this project and are on file in the City of Carlsbad Planning Department located at 1635 Faraday Avenue, Carlsbad, California, 92008. 1.

The surveys will consist of three visits, one week apart; the last of these will be conducted no more than three days prior to construction. • Surveys will also be conducted by a qualified biologist in appropriate habitat for nesting raptors and migratory birds (including, but not limited to the least Bell's vireo) and within an additional 500-ft buffer within three days of construction. • The USFWS will be notified immediately of any federally listed species that are located during pre- construction surveys. • If nests of listed birds, migratory birds, raptors, or other sensitive species are located, they will be fenced with a protective buffer of at least 500 feet from active nests of raptors and listed species, and 300 feet from other sensitive bird species. All construction activity will be prohibited within this area. • During the breeding season, construction noise will be measured regularly to maintain a threshold at or below 60 dBA hourly Leq within 500 feet of breeding habitat occupied by listed species. If noise levels supersede the threshold, the construction array will be changed or noise attenuation measures will be implemented. In order to comply with the HMP guidelines, there will be a no net loss of native vegetation communities within the Hardline Conservation Areas. Mitigation Measures for Sensitive Vegetation Communities BIO-2 A biological monitor shall be present during the construction process in order to review the limits of work and Best Management Practices (BMPs) prior to commencement of construction and to periodically check the compliance of environmental regulations. BIO-3 BMPs should be applied that result in the open-trench area, staging area, and drill rig to specifically avoid indirect impacts to the coastal and valley freshwater marsh. These should also apply to minimizing or avoiding disturbance to coastal sage scrub, chaparral, southern willow scrub, and the mapped locations of California adolphia (Adolphia californica). Such BMPs may include installation of silt fencing and dust control measures. BIO-4 In order to avoid impacts to vegetation communities from the possibility of an escape of the bentonite slurry into the environment (frac-out), the project contractor will submit an Emergency Frac- Out Containment Plan to the Engineering Department. The plan will outline actions to be taken in the event a frac-out occurs. The plan shall include a requirement to immediately notify the biological monitor and for the monitor to conduct an assessment of biological impacts. 30 Rev. 12/13/07 EIA 08-01 LA GOLONDRINA & LA COSTA MEADOWS SEWER EXTENSIONS APPLICANT CONCURRENCE WITH MITIGATION MEASURES THIS IS TO CERTIFY THAT I HAVE REVIEWED THE ABOVE MITIGATING MEASURES AND CONCUR WITH THE ADDITION OF THESE MEASURES TO THE PROJECT. , 200?
